Spectral (or optical) resolution is one of the most essential characteristics of a spectrometer. A system’s spectral resolution determines the maximum number of spectral peaks that can be resolved by ...

UC Davis electrical engineers have created a chip-sized device to measure the spectrum of visible and infrared light. The spectrometer-on-a-chip could have a wide range of applications in medicine, ...

A spectrometer is an imaging system used to map plurality of monochromatic images of the entrance slit onto the detector plane. This slit determines the amount of light (photon flux) that enters the ...

University of Illinois chemistry professor Alexander Scheeline has developed software that turns a camera phone, an LED, and a few other cheap tools into a spectrometer. Armed with these, he thinks we ...

Researchers developed a multi-channel mass spectrometry system that processes ions in parallel, enhancing signal detection, ...

A reengineered mass spectrometer prototype can now analyze up to a billion molecules simultaneously, a leap from conventional ...

A portable spectrometer small enough to fit inside a smartphone camera could soon be used to diagnose diseases including skin cancer. As well as diagnosing diseases the portable spectrometer could ...

When we hear spectrometer, we usually think of some piece of high-end test equipment sitting in a CSI lab. Sure, a hacker could make one if he or she put their mind to it. But make one out of a webcam ...

There is always something interesting to find when browsing the projects on Hackaday.io. I’m always amazed at how much hackers can get done in their basements and home labs. One surprising trend I’ve ...

Scientists at The Rockefeller University have built a prototype mass spectrometer that can process over a billion molecules ...
